PURPOSE: A cast iron gas burner is provided to prevent the extinguishing of fire on a combustion plate due to external wind by mounting an iron metal material cylindrical windshield. CONSTITUTION: A cast iron gas burner comprises a supporting protrusion(2a), a bonding groove(3a), a vent hole(3b), and a windshield(3). The supporting protrusion is formed in the upper side of a combustion plate at the constant height. The bonding groove is formed in a cast iron metal material cylindrical body in order to be installed on the upper side of the combustion plate of the cast iron gas burner. The bonding groove is formed on a main wall to be opened downstream at a regular interval. The vent hole is combined in the supporting protrusion of the combustion plate. The windshield comprises a fixed protrusion(3c) with the fixing grooves on both end of the main wall.
